PORTABLE DEVICE TO MEASURE AND CONTROL ANALYTES IN BIOLOGICAL LIQUIDS Russian patent published in 2012 - IPC G01N33/48 A61B5/1486 A61B5/1495 

FIELD: measurement equipment.

SUBSTANCE: invention relates to the field of analytical chemistry and may be used to measure analytes (substances defined during analysis) in biological liquids. A portable device to measure and control analytes in biological liquids comprises the following: one disposable metering cell (20) for applying onto patient's skin, a metering unit (21), connected with the metering cell (20), a remote control unit (22), connected with the metering cell (20) and with the metering unit (21). The metering cell (20) and the metering unit (21) are arranged in the form of separate modules and are connected with each other by means of electric connections (36, 37) and capillary tubes (25, 26). The metering cell (20) comprises the following: a subcutaneous probe (28), a fermentative cell (29), connected to the subcutaneous probe (28) by means of a hydraulic connection (42), a thermal sensor (30), connected with the first capillary tube (26) at the output of the fermentative cell (29), an element comprising a glucose sample (32) for functional inspection of a system prior to introduction of the subcutaneous probe, and a separator of air bubbles (33).

EFFECT: higher accuracy of measurement with lower voltage of polarisation at electrodes.
